I have a custom object:
public class Cat {
private String mName;
private int mAge;
public Cat(String name, int age) {
mName = name;
mAge = age;
}
@Override
public String toString() {
return mName;
}
}
I need to get String[] with names from Cat[]. It it possible? How to get it?
As assylias wrote in the comments - you will iterate it one way or another, that said, if you don't want to explicitly iterate it - you can use Arrays.toString :
Cat[] catArray = ...
String catArrayStr = Arrays.toString(catArray);
考虑使用延迟评估的Google Guava的transform
,因此在使用时仅迭代一次。
